Lemmings is a puzzle computer game, developed by DMA Design (now Rockstar North) and published by Psygnosis in 1991, originally for the Commodore Amiga. Lemmings was one of the most popular computer games of its time and several games magazines praised the game, giving it some of their highest review scores at the time. The popularity of the game led to development of numerous ports to other systems, including most recently ports to the PlayStation Portable, PlayStation 2, and PlayStation 3 in 2006 and 2007, and the creation of several sequels.
The behavior of the creatures in Lemmings is based on the behavior of real lemmings, who are known to go on migrations en masse that eventually lead to disaster. In order to save at least the required number of lemmings, the player must determine how to assign a limited number of eight different skills to specific lemmings that allow the selected lemming to alter the landscape, to affect the behavior of other lemmings, or to clear obstacles in order to create a safe passage for the rest of the lemmings, sometimes even by means of sacrifice.
